Remarks on result:

other: chromium(3+) ion hydrogen bis(1-(3-chlorophenyl)-4-[(E)-2-(5-methanesulfonyl-2-oxidophenyl)diazen -1-yl]-3-methyl-1H-pyrazol-5-olate) not ignited when the flame of bunsen burner having temperature of approximately 950°C was brought in contact with it.

Interpretation of results:

other: non flammable

Conclusions:

Chromium(3 +) ion hydrogen bis(1 -(3 -chlorophenyl)-4 -[(E)-2 -(5 -methanesulfonyl-2 -oxidophenyl)diazen -1 -yl]-3 -methyl-1H-pyrazol-5 -olate) does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that chromium(3 +) ion hydrogen bis(1 -(3 -chlorophenyl)-4 -[(E)-2 -(5 -methanesulfonyl-2 -oxidophenyl)diazen -1 -yl]-3 -methyl-1H-pyrazol-5 -olate) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus chromium(3 +) ion hydrogen bis(1 -(3 -chlorophenyl)-4 -[(E)-2 -(5 -methanesulfonyl-2 -oxidophenyl)diazen -1 -yl]-3 -methyl-1H-pyrazol-5 -olate) was considered non-flammable for chemical safety assessment.

Executive summary:

Chromium(3 +) ion hydrogen bis(1 -(3 -chlorophenyl)-4 -[(E)-2 -(5 -methanesulfonyl-2 -oxidophenyl)diazen -1 -yl]-3 -methyl-1H-pyrazol-5 -olate) does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that chromium(3 +) ion hydrogen bis(1 -(3 -chlorophenyl)-4 -[(E)-2 -(5 -methanesulfonyl-2 -oxidophenyl)diazen -1 -yl]-3 -methyl-1H-pyrazol-5 -olate) is not flammable at high temperature.
